葡萄的枝蔓和芽眼比较耐寒,而根系在零下4℃时就会出现轻度冻害,零下5℃至零下7℃就会冻死。 在寒露到冬至前后,要把秋剪后的葡萄下架放在沟里,晚上用草袋盖上,白天打开,霜降前灌1次透水。封冻前的这段时间葡萄处在休眠期,要适时防寒。各地常用的防寒方法有以下几种: 一、沙埋或土埋防寒 先将冬剪的葡萄枝蔓顺沟捆扎好,用沙子或土覆盖20～30厘米厚,然后待土冻10厘米厚时,再用树叶和柴草覆盖50厘米,四周延出1米,同时竖埋几个小秫秸,上端露出,起通风透光作用。
Grape vine branches and bud eye relatively cold, while the roots at minus 4 ℃ there will be mild frost damage, minus 5 ℃ to minus 7 ℃ will freeze to death. In the cold dew to the winter solstice before and after the autumn scissors to put the grapes in the ditch, covered with grass bag at night, open during the day, before pouring a flood pervious to frost. Frozen grape during this period of time in the dormant period, to be timely cold. First, the sand buried or buried in the first cold winter grape vine branches Shuigou ditch well, with sand or soil cover 20 to 30 cm thick, and then until the soil is frozen 10 cm thick, And then covered with leaves and firewood 50 cm, extending 1 meter around, while buried a few small sod straw, exposed at the top, play a role in ventilation and light.
